Traps

From The Cataclysm: Dark Days Ahead Wiki
Jump to: navigation, search

Traps can be found as part of environment, stash map extra, and can be constructed or set up from items by player (most of these can be crafted). Traps can be placed only on perfectly flat surface (with 100 moving points cost). One tile can contain only one trap. Movement points required to set up a particular trap are equal to the awarded practice percents multiplied by 25, plus an additional 100.

A given trap is visible to a character if

perception − (eye encumbrance + trap visibility)

is zero or greater. If a player tries to step on a visible trap, the game will ask to confirm that movement.

Avoidance

Trap avoidance is determined by two dice rolls, one for the trap and another for its victim. If victim's roll is lower than the trap's roll, then the victim springs the trap.

Trap dice is:

  • 6d[ Avoidance ] for invisible traps.
  • 3d[ Avoidance ] for visible traps or if a critter steps on it.

Victim dice is:

  • 3d[ dodge skill + 1 ] for critters.
  • 3d[ current dexterity + dodge skill * 1.5 ] for the player character, and Light Step trait gives a (low) bonus of 2d6 to the player character's roll. However if player has Clumsy, 2d6 is taken away from the player character's roll instead.

Flying and digging enemies are fully immune to traps.

Disarming

Traps can be disarmed only when visible, though traps with 99 difficulty give no disarm option upon examination at all.

The success of a disarm attempt is based on a dice roll. This disarm roll is a random number from the player's traps skill level to their traps skill level multiplied by four. The disarm roll may be increased further (up to 50) based on the player's current perception and dexterity. (If perception is greater than a random number from 5 to 20, or if dexterity is greater than a random number from 1 to 20, the roll will be increased by 1. This process repeats until both checks fail or the roll reaches 50.)

If the disarm roll is greater than or equal to the trap's difficulty, the player successfully disarms the trap and receives its items; if the roll is less than the trap's difficulty, but greater than or equal to 80% of the difficulty, disarming will fail without setting the trap off. In both cases, the character will gain 1.5*(trap_difficulty - traps_skill_level) practice points.

If the player sets off the trap during the disarm attempt (meaning the disarm roll was less than 80% of the amount needed), but the difference between the trap's difficulty and the player's roll is less than or equal to 6, the character will gain 2*trap_difficulty practice points.

Disarming a trap is currently a free action. For reference purposes, an unmodified human--such as the typical starting character--receives 100 move points per turn, so losing 100 move points would force the player to be there and do nothing for a turn.

Trap tools

These are the traps you can arm yourself. Activate the item and you will be asked where to place the trap. If you choose a place that already contains an invisible trap, that trap will be triggered. In any case, you can not set a trap on another trap.

Trap-like tools

These are items that share the traps functionality, although they aren't traps themselves. They don't require any skill to being able to arm or disarm them.
